- MidasPlus - Molecular Interactive Display and Simulation System
- Computer Graphics Laboratory
- University of California, San Francisco
-
-
- MidasPlus is a sophisticated molecular modeling system developed
- by the Computer Graphics Laboratory at the University of California,
- San Francisco. The system is used daily in a university-level
- research program for the display and manipulation of macromolecules
- such as proteins and nucleic acids. Ancillary programs allow for
- such features as computation of molecular surfaces and electrostatic
- potentials and generation of "publication quality" space filling
- images with multiple light sources and shadows. Because of our
- own research needs, MidasPlus has been developed with an emphasis
- on the interactive selection, manipulation and docking of drugs
- and receptors. Although quite powerful in this application, the
- system is also somewhat specialized in this respect: it requires
- three dimensional atomic coordinate data for the structures being
- displayed and expects the primary structure to be based on linear
- chains of subunits such as amino acids or nucleic acids. Complex
- inorganic compounds and large polymers with many crosslinks are
- handled ungracefully. See the MidasPlus User's Manual for full
- details.
-
- MidasPlus was initially developed in the early 1980's, and until
- recently has run only on high performance interactive graphics
- workstations such as the Silicon Graphics IRIS. Versions are now
- available the NeXT family of workstations, the SGI IRIS family of
- workstations, and the DECstation 5000 PXG family of workstations.
- Because of the lack of full support for doing three dimensional
- image rotations and translations using the NeXTDIMENSION graphics
- option prior to NeXTSTEP 3.0, the current version of MidasPlus for
- the NeXT can effectively handle only small proteins, nucleic acids
- and drug models. A color system is essential for serious modeling
- work, although the software is capable of running on a black and
- white NeXTSTATION as well. As with most workstations, the more
- main memory you have the better the application will perform; we
- consider 20MB on a color NeXTSTATION and 32MB on a NeXTDIMENSION
- system to be adequate. If you plan to work with many models, 400MB
- of disk should be considered an absolute minimum.

-
- The distribution of MidasPlus included on this "NeXT Public Domain
- CD-ROM for Education" is a binary-only version of the system. It
- has been tested extensively under NeXTSTEP release 2.1 and in a
- much more limited fashion under NeXTSTEP 3.0 beta pre-release 2.
- This version does NOT use Interactive RenderMan (IRM), and hence does
- not take advantage of the high performance 3D graphics available with
- the NeXTDIMENSION option under release 3.0.
-
- MIDASPLUS IS COPYRIGHTED BY THE REGENTS OF THE UNIVERSITY OF CALIFORNIA.
- THE BINARY-ONLY VERSION OF MIDASPLUS INCLUDED ON THIS CD-ROM IS LICENSED
- ON A PER WORKSTATION BASIS FOR $99 PER COPY. A ONE WEEK "DEMO LICENSE"
- IS AVAILABLE FREE OF CHARGE. SEE BELOW FOR DETAILS ON NOW TO OBTAIN
- THE LICENSE PASSWORD NECESSARY FOR ACTIVATING THE MIDASPLUS APPLICATION.
-
- You must install MidasPlus on your hard disk in order to use it. The
- MidasPlus application and assorted support programs take approximately
- 2 MB of disk space and reside in the directories /LocalApps, /LocalLibrary,
- and /usr/local/{bin,lib,man}. Use the standard NeXT Installer application
- to do the installation. You do not need to install the compressed PostScript
- documentation if you just want to print it. If you want the MidasPlus
- manual pages to be seen by the Digital Librarian and the UNIX "man" command,
- you will need to make a couple of symbolic links after you have run the
- Installer App.. On a NeXTSTEP 2.{0,1,2} system do (as root):
-
- ln -s /usr/local/man/manl /NextLibrary/Documentation/Unix/ManPages/manl
- and
- ln -s /usr/local/man/catl /NextLibrary/Documentation/Unix/ManPages/catl
-
- On a NeXTSTEP 3.0 system do:
-
- ln -s /usr/local/man/manl /NextLibrary/Documentation/ManPages/manl
- and
- ln -s /usr/local/man/catl /NextLibrary/Documentation/ManPages/catl
-
-
- The binary-only distribution of MidasPlus contains no source code
- and no printed documentation, but otherwise is a fully functional
- release. PostScript versions of the MidasPlus User's Manual
- (manual.ps.Z), MidasPlus Command Quick Reference Card (quickref.ps.Z),
- and Version 1.8 Release Notes (release-notes.ps.Z) are included in
- this directory. The manual is 130 pages in length and fully documents
- the MidasPlus system. Serious users are encouraged to print out the
- manual and study it carefully to determine the many features and
- limitations of the system. A "show and tell" style introduction to
- MidasPlus can be found in the "Demos" directory. Additional demos
- can be found in Demos/{dna,crodna} and a PDB model of the protein
- Glucagon can be found in /LocalLibrary/Mol/pdb. See the individual
- "README" files in each of the subdirectories for demo operating
- instructions.
-
- MidasPlus is also licensed in source form to universities and other
- organizations. The license fee is $350, which includes complete
- source code, distribution media, machine readable and printed
- documentation, and our administrative overhead costs. Support and
- training are not available, although we do welcome bug reports and
- periodically issue update releases that incorporate bug fixes.
- Please note that we are an academic institution with limited personnel
- and not a commercial software company.
-
- To obtain either a free one week demo license or a $99 per workstation
- binary-only license for the MidasPlus software system, do the following:
-
- 1. Install the MidasPlus package on your NeXT workstation
- hard disk by double-clicking on the Midas.pkg icon.
-
- 2. Start up MidasPlus by double-clicking on the /LocalApps/Midas
- icon. A alert panel will pop up showing the unique machine
- identifier for your workstation.
-
- 3. Send an email message to midas-license@cgl.ucsf.edu (Internet),
- or send US mail to the address shown below, or call 415-476-5128
- and ask to speak with the MidasPlus license coordinator. You
- must supply the following information:
-
- a) Name
- b) Title
- c) Instutional affiliation
- d) Address
- e) Phone number
- f) Machine identifier
- g) A check or purchase order for $99 (optional).
-
- 4. A 16 digit license password will be returned to you. Add
- this password along with your machine identifier to the list
- of passwords in /LocalLibrary/Midas/demo_passwords and then
- double-click on the /LocalApps/Midas icon.
-
- 5. In order to run the overview demo on a 3.0 system, or to be
- able to double-click on files with .pdb extensions, you will
- either need to logout and log back in again, or wait until
- the workspace manager discovers MidasPlus has been installed.
-
- License requests which do not include a check or purchase order will
- receive a one-week license free of charge (one time only). Requests
- with include payment will receive a license password good for ten years.
- If your payment is via a purchase order, it will take time for the
- purchase order to be processed before your license is issued (some
- institutions and government agencies are very slow in paying, so you
- may wish to consider paying by check in order to avoid potential delays).
